Answer:108 houses

Step-by-step explanation:

Step 1: ratio of flats to bungalows is 10:5 and the bungalows are 30, therefore:

(10*30)/5 = 60 flats

Step 2: the ratio of houses to flats is 9:5 and the number of flats is 60, therefore

9*60/5 = 108 houses

Answer:

$a=8\\b=10\\c=5$

Step-by-step explanation:

In the given image, you can observe we have two right triangles.

Also, we know by given that those triangles are similar, which means their sides are proportional and their angles are congruent.

If the triangles are similar, we can define the following proportion between sides.

$\frac{4}{a} =\frac{3}{6}\\ 24=3a\\a=\frac{24}{3}\\ a=8$

Now we use the Pythagorean's Theorem to find each hypothenuse.

$c^{2} =4^{2} +3^{2}\\ c=\sqrt{16+9}=\sqrt{25} \\ c=5$

$b^{2} =8^{2} +6^{2}\\ b=\sqrt{64+36}=\sqrt{100}\\ b=10$

Therefore, the missing sides are

$a=8\\b=10\\c=5$
